that each fisherman will becor.e experienced in his special job. Af foi* /';, 

 study should be made of the use of large branches nixed in with the albacore 

 lines so as to catch large fish such as big-eyed tuna and narlins. 



d. Fishing grounds 



The fishing grounds vary with the season, but in Areas T pnd XT 

 investigations should be nade as far north ns the vvnrn currents go to areas 

 with water tenperatures of about 10 . In the investigations nade up to now 

 fishing has been good at temperatures of between 13" and 16.5°. Furtherrore, 

 since the North Pacific is very caln in the suraner season, means should be 

 devised to advance efficiency to utilize this period fully, and policies 

 should be developed fully to cope with the notoriously storny weather of 

 late autunn and winter. Also thorough studies should be rade with a view 

 to extending the fishing grounds north to the vicinity of the Aleutians, 

 northeast toward the continent, and to the vjators off Japan. 



e. Fishing seasons
